TUCKING-G UIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 712,195, dated October 28, 1902.

Application filed January 27, 1902. Serial No. 91,444. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, RICHARD J .-KELLEY, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Tuck-Folders for Sewing Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact descrip tion.

This invention relates to the class of attachments for sewingmachines which are designed for the purpose of accurately and uniformly folding the fabric fed to the machine-needle in the operation of forming tucks in the fabric.

The object of the present invention is to produce a device of the aforesaid class which shall be applicable to any well-known sewingmachine and which shall be more simple in construction, more efficient in its operation, and shall permit of easy, quick, and convenient adjustment when desired to form tucks of various sizes; and, furthermore, the object is to produce a device which can be readily employed in the operation of sewing cordsin the fabric and at the same time shall be inexpensive in its manufacture.

To that end the invention consists in the novel construction and combination of parts, I

as hereinafter fully described, and set forth in the claims.

In the accompanying drawings, Figure l is a plan view of a tuck-folder embodying my invention. Fig. 2 represents a side view of the same, and Fig. 3 is a longitudinal section on line ac to in Fig. l and showing by dotted lines the adaptability of the device for sewing cords in the fabric.

Similar letters of reference indicate corresponding parts.

Arepresents the bed of the sewing-machine, and B denotes the main supporting-plate of the improved tuck-folder, which plate is provided with a slot at for the reception of a screw 1), by which it is secured adj ustably to the bed A. The plate B is formed with an arm O,which extends laterally from said plate and at right angles to the slot a, as shown in Fig. 1 of the drawings.

The arm 0 of the main plate A is formed with a fold-gage d, formed thereon parallel with the shoulder c. The supplemental plate is provided with the usual gaging-marks c and is seated between upwardly-projecting ears f f, formed on the main plate, or, more properly,'the arm 0, said ears serving to guide the supplemental plate and sustainit laterally in its adjusted position.

The top of the arm 0 adjacent to the shoulder or fold-guide c constitutes astationary.

jaw for sustaining the supplemental plate D,

which is clamped adjustably on said stationary jaw by means of a movable jaw g, which I preferably pivot at one endin vertically-elongated eyes h h inthe ears f f to allow vertical movement of said portionof the jaw.

Over the free end of the jaw g is a cam-lever t, pivoted to the ears and forced to bear onto the jaw by pressure applied to the free end of said cam-lever,as shown in Figs. 2 and and described for pressing the movable jaw onto the supplemental plate, inasmuch as other means may be employed for the purpose.

My improved tuck-folder is adapted to be used for sewing cords in the fabric by placing the supplemental plate D in a position to carry the fold-gage d into proximity to the abrupt shoulder or fold-guide 0, so as to hold between said gage and shoulder or guide the portion of the fabric inclosing the cord, as indicated by dotted lines in Fig. 3 of the drawings. By said adjustment the cord-containing portion of the fabric is carried past the line of sewing to the needle n.

What I claim as my invention is 1. In a tuck-folder for sewing-machines, the combination of a main plate provided with means for securing the same adjustably to the machine-bed and formed with a stationary jaw at one end and a fold-guide extending along the front of said jaw, a pair of upwardly-projecting ears at opposite ends of said jaw, a supplemental plate mounted longitudinally adjustable on said stationary jaw and disposed between said ears to be guided thereby and formed at its free end with a tuck-gage, a jaw pivoted to said ears above said supplemental plate, and a cam-lever pivoted to said ears and engaging said pivoted jaw whereby the latter is pressed firmly onto the supplemental plate to confine the same in its positionas set forth.

2. In a tuck-folder for sewing machines, the combination of a longitudinally-slotted main plate provided with a set-screw whereby the same is secured adj ustably to the bed'of the machine, and formed with a stationary jaw at one end and a fold-guide extending along the front of said jaw, a pairof upwardlyprojecting rigid ears formed at opposite ends of said stationary jaw and provided with vertically-elongated eyes, a jaw pivoted in said eyes above the stationary jaw, a supplemental plate disposed longitudinally adjustable between said jaws and formed at its free end with a tuck-gage, and a cam-lever pivoted to said ears and pressing onto the free end of said pivoted jaw, whereby the said supplemental plate is firmly clamped in its position as set forth and shown.

3. In a tuck-folder for sewing-machines, the combination of a longitudinally-slotted main plate provided with a set-screw whereby the same is adjustably secured to the machinebed, and formed with a laterally-extending arm disposed at right angles to the slot, a stationary jaw formed on said arm and a foldguide disposed on the front of said jaw, a pair of upwardly-projecting ears formed at opposite ends of said jaw and provided with vertically-elongated eyes, a jaw pivoted in said eyes and arranged above the stationary jaw, a supplemental plate mounted longitudinally adjustable on said stationary jaw and formed at its free end with a tuck-gage, and a camlevezr pivoted between said ears and adapted to bear on the pivoted jaw whereby the said supplemental plate is firmly clamped in its position as set forth.

4. In a tuck-folder for sewing-machines, the combination with a main plate provided with means for securing the same adjustably to the bed of the machine and formed with a stationary jaw at one end and a fold-guide extending along the front of said jaw, a pair of upwardly-projecting ears formed at opposite ends of said jaw, a supplemental plate mounted longitudinally adjustable on said stationary jaw and disposed between said ears to be guided thereby and formed at its outer end with a tuck-gage, a movable jaw sustained between said ears above the supplemental plate, and means adapted to engage said movable jaw to cause the latter to press firmly'onto the supplemental plate to confine the same in its position as set forth.

5. In a tuck-folder for sewing-machines, the combination of a main plate provided with means for securing the same adjustably to the machine-bed and formed with a laterallyextending arm disposed substantially at right angles to said plate, a stationary jaw formed on said arm and a fold-guide disposedat the front of said jaw, a pair of guides on said stationary jaw, a supplemental plate mounted longitudinally adjustable on the stationary jaw and movable between said guides and formed at its outer end with a tuck-gage, a movable jaw sustained between said guides above the supplemental plate, and means adapted to engage said movable jaw whereby the supplemental plate is firmly gripped between said jaws to confine the tuck-gage in the desired position in relation to the aforesaid fold-guide as set forth.
